2. Powerbank - eto uso na ngayon, it's like an external battery pack or back up battery where you can charge your gadgets.
At first, I thought I don't need one. I always charged my cellphone and Tab naman kasi. But last week, super lowbat CP ko because of brownout, kaya we immediately bought powerbank kahit maliit lang, worth P300. But we need 20000 mah as per my officemate so we can use it longer, I think nasa P2,000 daw yun eh.
